I don't see why there wouldn't be an actual number displayed already instead of just showing 40 / 50 / 60 / 70 / 80% AD in the tool tip. That's good to know, but I shouldn't really have to math it out myself if I want to see how much damage it's doing, especially if I want to be a special snowflake and play AD Kennen.
Its a ration on his AD there is no flat damage number to give on the fact is there is no flat damage that occurs. Basicly you do need to do the math if you want to play AD kennen BUT its only the Charged Auto Attack that gets this ratio. So take kennens total AD then take that number and add the ratio then thats your Raw damage on auto attacks with the charged Auto Attack.
They can't put a number on it without lowering the ratio because its already using his basic attack damage on top of a amp damage from the passive. Kennen can have many def starting attack damage depinding on runes and masterys, another reason why there is no flat number added.
It does that? It should show it, everything else does... So few things show the percentage, and they ALL show the amount it does (thinking of Dravens Q)...
Basically you take your attack damage ex: 153 you move one decimal over so 15.3 * 4/5/6/7/8= the extra damage. Just add the mixed number every time you put a point into your w. Basically for every 10 ad (because 1 ad would be .1 bonus dmg) you multiply however many points you have in w so 4/5/6/7/8 so with 3 points in your w 10 ad adds 60 dmg so on so forth.
